LUBBICATING, nnvron.

Application filed June 7, 1924. Serial No. 718,491.

This invention relates to lubricating devices for vehicle springs.

Among the objects of the invention is to provide a simple and practical device of the character described which shall be adjustable to various sizes and shapes of spring, may readily be applied to or removed from the spring, and shall belhighly el'licient and economical in operation.

A further object of the invention is to provide a neat appearing lubricating device of the character described in the form of a unitary wrapper which may be comparatively cheaply manufactured, and which shall be reliable and positive in operation.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of Which the scope of application will be indicated in the following claims.

1n the accompanying drawing,in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a perspective view of a portion of a spring cover embodying the invention;

Fig. 2 is a plan View looking up from the bottom of Fig. 1;

Fig. 3 is a view corresponding to a midcross-section taken on Fig. 1; and

Fig. 4 is a view of the'device opened flat showing the interior construction.

Referring to the drawing, 10 denotes a portion of a laminated vehicle spring of any usual construction, and 11 a lubricating device embodying the invention mounted thereon, and embracing all the leaf end portions of the spring 10. Device 11, preferably is formed of suitable flexible material, and comprises an outer oil proof fabriccover 12 of fpantasote, leatherette, leather, or the like material, and an oil-absorbing lining 13 of fibre, felt, or other suitable material. The cover 12 may have along the marginal edges thereof binding strips 12, the ends of which are aranged to be tightly drawn together by any suitable means, as for example adjustable clasps 14 (see Fig. 2). The device 11 may easily and quickly be applied to the spring portion 10 by simply wrapping said device 11 about the latter and may then be secured in place by clasps l4 and a parallel set of spaced hooks provided along each edge of the cover 12, through which a lace 16 is cross-drawn as shown in Figs. 2 and 3. A tongue-flap 17 may be provided for covering the gap between the lace-drawn edges of cover 12 to completely shield the interior of the device from dirt particles and the like, and to prevent dripping and leakage of the lubricant.

The device 11 ispreferably mounted so that the clasps 141 and lace fastening are on the bottom side of spring portion 10, the top side be ing provided with an opening 18 through which the lubricant is supplied, and a snap button closure 19 or other means, for said opening 18.

Two spaced parallel strips 20 of felt or the like material are secured to the lining 13 to extend lengthwise thereof on each side of opening 18 to form a channelshaped lubricant reservoir 21 when device 11 is in proper place on spring 10 as shown'in Figs. 3 and 4:, and the end portions 20 of said strips 20 may be chamfered down to form an obstruction at the ends of said channel receiver 21 against the free flow of the lubricant therefrom.

From the drawing and the above description, it will be obvious that the cover 12, lining 13, flap 17, the spaced strips 20, marginal binding strips 12 and clasps 1 1 are all permanently united to form a single wrapping structure whereby said device 11 may be adjuster l to various sizes of springs, and quickly applied to or removed from the spring 10 as a unit to permit ready accessibility of the spring leaves. The lining 13 entirely surrounds the parts of spring 10 (see Fig. 3), and provides an ellicient and simple medium for distributing the lubricant from reservoir 21 to all surfaces needing lubrication, the side strips 20 of the res ervoir 21 being relatively thin and porous enough to permit seepage of the lubricant therethrough to lining 13 for said distribution.

It will be noted that the described fastening construction also provides means whereby any looseness in fit of the device 11 on spring 10 may be taken up.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made at the above invention, and as various claim as new and desire to secure by Letters Patent 1 A lubricating device for vehicle springs comprising an outer oil proof fabric cover and an integral inner absorbent lining attached thereto at the longitudinal edges of the cover, and two spaced relatively thin vstrips of absorbent material secured lengthwise of said lining on theinner side thereof adapted to forma reservoir having porous wall portions for .a lubricant when said device is properly adjusted on a portion of a spring, to form a unitary flexible wrapping structure.

2. A lubricating device for vehicle springs comprising an outer oil proof fabric cover and an integral inner absorbent lining of uniform thickness attached thereto, and two spaced relatively thin strips of absorbent material secured lengthwise of said lining adapted to form a reservoir having porous wall portions for lubricant when said device is properly adjusted on a portion ol a spring, and means secured to the cover for completing the closure thereof about said spring portion, said cover, lining, strips and means being permanently secured togetl'ier to form a single unitary flexible wrapper.

In testimony whereof I a'flix my signature.

EDWIN B. N'ATHAN.
